I absolutely love these energy shots. They're typically pretty expensive and I drink one a day (instead of coffee). I found a good deal on iHerb.com, they arrived quickly, but they must have been stored improperly. Even with good expiration dates, seven out of twelve smelled sour and had big chunks of something floating in them. Luckily, I wrote to the manufacturer and they replaced them. I will not buy anything from iHerb.com again.
